The Glucose-6-Phosphate Dehydrogenase (G6PDH) Activity Assay Kit is primarily used to measure the enzymatic activity of G6PDH in various biological samples. This assay is crucial in research and clinical settings to assess G6PDH deficiency, a genetic disorder that can lead to hemolytic anemia. It is also employed in studying cellular metabolism, particularly the pentose phosphate pathway, which plays a key role in generating NADPH and ribose-5-phosphate. The kit is widely used in biochemistry and molecular biology labs to investigate oxidative stress, redox balance, and the impact of drugs or toxins on G6PDH activity. Additionally, it aids in quality control for pharmaceutical and food industries, ensuring the stability and functionality of products dependent on G6PDH activity.
